At a Glance (2/3):Reflects 50% of 2 elements: light, and earth. Cannot use two at once, though that's not really an issue.

In-Depth (2/4):This has the utility of both Shovel Plus and Expert Lens. Numerically speaking, it's like Pirate Captains Hat, but without the fire defense, the semi-fragility (you would break even with either weapon if you got hit with earth and/or light), and the price. But like the other two reflectors above, you will be faced with the same limitations: the difficulty to win against mass earth constants, and the potential redundancy for the defense of a rarely utilized element.

Price (1/2):I can never keep up with the price of this thing. It's worth less than it currently is at the moment, and it will stay that way for awhile as long as people try to keep the price up (even though supply will eventually get the better of them). I personally think its worth ~500k-700k, no more than 1 mil.

Bonus (1/1):I find it really ironic that it's better than Princely Lens... I also find it ironic that having one less element from Kings Lens constitutes a price drop of ~39-49m (it does make quite a difference though!).
